In this article, you'll learn how Maintenance by Metric lets you do the following:
- Set up and track multiple cumulative reading types for system components
- Schedule maintenance checklists based on more than one cumulative reading type
- More accurately predict when maintenance routines will be due
In Helm CONNECT Maintenance, a "cumulative reading type" refers to a metric, such as running hours, where values only ever increase. Cumulative reading types aren't used to indicate that something is "out of spec," or outside the range of normal or expected operation.
To get you started, we provide two default cumulative reading types: Running Hours and Fuel Used. You can create one more cumulative reading type for whatever you need, and you can also edit or delete the Fuel Used reading type if you need something different (as long as the reading type isn't actively in use in any maintenance templates or published checklists).
If you don't need to incorporate fuel burn, or any other cumulative reading, into your maintenance plan, you won't need to make any changes to Helm CONNECT. Your running hours schedules on your maintenance checklists will work the same as they did before.
Note If you use the Fuel Used reading type, note that it's not a "fuel tracker" tool; it's designed to track only fuel consumption for maintenance purposes. It can't be used for billing within Helm CONNECT Jobs or to track how much fuel is in the tank.
Set up cumulative reading types
You can define up to three cumulative reading types in Helm CONNECT.
To set up cumulative reading types
- Go to the Setup > Operations > Reading Types tab.
- Click New Reading Type.
- In the Name field, enter the full, descriptive name of the reading type.
- In the new Display Name field, enter a short name (20 characters or fewer) for the reading type. This will be the label that appears with the reading type wherever it occurs in Helm CONNECT. We recommend including the reading type, for example, Running Hours or Fuel Used, in the display name for clarity.
- In the Units field, enter the required units for the cumulative reading type.
- Select the Cumulative check box.
Once you've saved a reading type, you can't change this check box.
- Click Save Changes.
The Display Name and Cumulative reading type information appear in new columns on the Setup > Operations > Reading Types tab list view.
Build maintenance templates using cumulative reading types
In previous versions, you could already build templates to record running hours for components and templates triggered by running hours milestones. In Version 1.17, you can still do this, and more.
Powerful schedule tool
You can schedule a maintenance template based on calendar date, on cumulative readings, or both. Whichever due schedule is reached first will trigger the checklist.
To help you do this, there are two tabs in the Schedule window:
- The Date tab works the same as the date schedule tool did in previous versions, except that the Frequency field no longer appears on this tab.
- The Cumulative Readings tab lets you define a schedule based on one or more cumulative reading types.
Note To display the Cumulative Readings tab, you need to select an asset and a component in the header of the maintenance template first.
You'll use the scheduling tool differently depending on what you want the maintenance template to do:
- Record cumulative readings: When scheduling a maintenance template designed to record cumulative readings for a component, you'll use the Date tab the same way you did in previous versions. For example, you could schedule the checklist to be due daily at a specific time.
- Schedule with cumulative readings: When scheduling a maintenance template to become due when selected cumulative reading values are reached, you'll use the new Cumulative Readings tab.
Add a cumulative reading item to a maintenance template used to record readings
When you add a Cumulative Reading item to a maintenance template, you can select any of the cumulative reading types defined in the system.
Important To prevent unusable or inaccurate data from accumulating in your system, we strongly recommend that you use a cumulative reading type only once per component within your maintenance templates used to record readings.
Schedule a maintenance template based on cumulative readings
You can build maintenance templates with schedules based on cumulative reading types.
To schedule a template based on cumulative readings
- In the maintenance template header, select an asset and a component, then click Create a Schedule.
Note The component you select will supply the cumulative reading values that determine when your maintenance template is due.
- On the Cumulative Readings tab, click Add Reading Type.
- From the Reading Type list, select the cumulative reading type you want to use for scheduling.
Note This list will display the reading types you defined on the Setup > Operations > Reading Types tab. Each reading type can have only one schedule item per template. If you use all of the available cumulative reading types, the Add Reading Type button becomes disabled.
- In the Est Daily Usage field, enter the expected typical daily usage rate for that reading type.
Example If you selected Running Hours in the Reading Type list, and the component you selected runs 24 hours a day, you would enter 24. If the component only runs 12 hours a day, enter 12.
Note The closer you get to typical usage values for this field, the more accurate the system will be when estimating when a checklist will be due.
- In the Frequency field, enter how often this maintenance checklist will be due, based on the reading type.
Example This could be 500 hrs for Running Hours or 6000 gallons for Fuel Used, whatever is required. Once you enter this information, the system will calculate the estimated due interval and display this value in the Due field.
- Click Save when you're done configuring the schedule.
A checklist scheduled to be due when target cumulative reading values are reached works in conjunction with other checklists used to record cumulative readings for the selected component. The system adds those recorded reading values to the values in the Due fields.
More about cumulative reading maintenance templates
Here are a few more tips to keep in mind when you're building maintenance templates that use cumulative reading types:
- You can use a Grouped Reading Category in templates designed to record readings when the same reading value will be added to multiple components. All fields in a grouped reading category will use the same cumulative reading type.
- For simplicity, clarity, and accuracy, we recommend keeping maintenance templates designed to record cumulative readings for a component separate from maintenance templates scheduled based on cumulative reading types.
